How do I export a registry hive?

29-Aug-03 4:54

There is an example of this very topic on the samples for VB.NET:

Private Sub DoesKeyExist
    Dim regVersion As Microsoft.Win32.RegistryKey
    regVersion = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\TestApp\\1.0", True)
    If regVersion Is Nothing Then
        regVersion = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("SOFTWARE\\Microsoft\\TestApp\\1.0")
    End If
End Sub

This will check to see if a key exists, then if not, creates it.
Oh yeah! It also needs a reference to the Win32 namespace.

I am using VB.net I am looking for a way to export a registry key like
HKLM\System\CCS\Control\Services (the whole key and all subkeys).

I would like to use the same methods that Regedit uses.

BTW: I am connecting to a remote machine's registry.

Question #2.
How do I determin the data type of a registry key. I understand how to read the value name and value but not the data type.
Example.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update

Value: AUState
Data Type: Reg_Dword <----This is what I am looking to discover.
Data: 2

It looks like RegEdit has its own enumerator built in. There is no function in the .NET framework that does the exact samething, so it looks like your going to have to write your own exporter.

The .NET framework doesn't offer a function to do what your want. Your probably going to have to write a C++ component to return that info.

I want to use SendMessage to send a WM_UPDATEUISTATE message that I hope will show the focus rectangle on option buttons but I cannot find the constant values for the expected wParam values: UIS_CLEAR, UIS_INITIALIZE, UIS_SET, UISF_HIDEACCEL, UISF_HIDEFOCUS, UISF_ACTIVE.

I know that I can change a setting in the Control Panel (Display - Appearance - Effects) but I want to be able to control this programmatically.

Any ideas?

If I read this right, you just want to move the input focus to a button control. In VB.NET, that's easy:

controlName.Focus()

will set the focus to that control. BUT!! (There's always one of these!)

Long version:
A control cannot receive focus unless it is enabled, is visible, AND HAS A WINDOW HANDLE ASSIGNED TO IT! What this means is, you can only set the focus to the control AFTER it has actually been created and it's Message Loop is up and running.

Short version:
If you try and set the focus to a control in a Form's Load event, you must first Show() the form, THEN set the focus to the control. Otherwise it won't work.

Thanks for the reply, but no. What I want to do is tell Windows to show a focus rectangle around the text of a button that has input focus. By default in XP it does not. Also, I am using VB6, not .Net.

If you search MSDN for the WM_CHANGEUISTATE Message you'll see exactly what I'm talking about.

On the other hand, if you have .Net and you search your local help file for the UIS_ and UISF_ constants specified in this tread's header, might you be able to tell me the numeric value of these constants?

For example, I know that...

WM_CHANGEUISTATE = 295 (H&0127)
WM_UPDATEUISTATE = 296 (H&0128)
WM_QUERYUISTATE = 297 (H&0129)

...but I do not know the value for these other constants and they are not known by VB6 because it pre-dates their use in the operating system (beginning with Win2000).

Dave Kreskowiak28-Aug-03 9:57

OK. I think I understand what your trying to do now.

I found the constants in WinUser.h in the VC98\Include folder. Here is the copy/paste:

/*
 * LOWORD(wParam) values in WM_*UISTATE*
 */
#define UIS_SET                         1
#define UIS_CLEAR                       2
#define UIS_INITIALIZE                  3

/*
 * HIWORD(wParam) values in WM_*UISTATE*
 */
#define UISF_HIDEFOCUS                  0x1
#define UISF_HIDEACCEL                  0x2
#if(_WIN32_WINNT >= 0x0501)
#define UISF_ACTIVE                     0x4
#endif /* _WIN32_WINNT >= 0x0501 */
#endif /* _WIN32_WINNT >= 0x0500 */
#endif

Rage,

Thanks a bunch. That is exactly what I was looking for. Unfortunately, my winuser.h file does NOT include these constants and frankly I don't know why (VB6 Enterprise).

I'll track that issue down next.

Granting "Logon As Service Rights"

Good gumba gumba! The whole SDK will take over 10 hours to download on my 56K! I'll spring 10 bucks for the CD by mail.

Thanks for the insight!

Anyone know how to grant a user account "Logon As Service" rights through VB/VBScript?

I'm trying to pre-install a couple of services, and although I have managed to get the WMI scripts working to create and run the services as the account in question, I cannot figure out how to grant the account logon rights without having to revert to using the old NTRIGHTS util.

Target OS are XP/2K, they are running both Stand-alone, on NT Domain or an Active Directory.

Meanwhile ... i will have to wsshell ntrights :-<

Cheers

I don't know how to do it off the top of my head, but the first question I have is: Is the .MSI being elevated to Admin level when it's run? Without this, you can't modify any use to Logon As Service.

My mistake, I should of mentioned that this is a straight VBS task (to be VBE'd later), and will be run from an Local Admin account.

Being a bit of a newbie to VB, I don't particually want to start fiddling with MSI just yet, it seems to be a bit OTT for the current purpose.

I have sort of found 2 ways around this. The first is to use NTRIGHTS.EXE but this means ensuring it's avaliable and that it can lookup the SID of the account that will require the rights. Unfotunatly this is not always possiable as it's a domian account that needs rights, and the service may need installing off-network (and NTRIGHTS won't take a SID as an argument).

The other method is to create on-the-fly a simplified Security Template then run "secedit /config /areas USER_RIGHTS ....." to apply the template. The only problem is if other user's have been given rights, the template wipes them out :-<

I haven't been able to find any scripting that will modify the Rights of a User Account. But, I can tell you that it is possible to do and it WILL require WMI to do it. Lucky for you W2K and XP both come with it native. 95/98/NT4 doesn't support WMI without first installing it seperately.

I'm still looking for a scripting solution...

Thanks for looking Rage, I can only assume you too are flummoxed!

I'm probably going to have to fall back on the security template method, assuming i can get 'secedit /export' to work so that I incorporate any previous security rights in the newly modified ones.

MDI Apps problems

Im a newbie when it comes to .Net technologies. Right now I am developing an MDI application using VB.Net. So this is my first .NEt project.

first question:

... why is that when the child form is being closed using the control menu (control box), the next time i click the menu item that should make the child form show up again, it won't show anymore?....

here's the code behind the menu item:

Private Sub mnuRR_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuRR.Click

If RRChild Is Nothing Then
RRChild = New frmReceivingOrders(Me)
End If

RRChild.Show()

End Sub

* RRChild is the child form
* mnuRR is the menu item of the parent form

... tnx Smile | :)

.. here we go again.

This is how I've opened my MDI child forms.

Dim RRChild as New frmReceivingOrders
RRChild.MdiParent=Me
RRChild.Show()

Hope this helps

We have a project that we recently split from one very large exe into 5 DLL projects. We have a greate deal of classes in each of the projects and we find that when we compile the program on a dev box there is a period shortly after the compile is completed where the app hangs for about 10-15 seconds.

Another of our guys had the same problem when at another site, where, once they had a large number of classes, VB was doing the same thing?

We have T30 and T40 IBM notebooks, so the processors and memory are fine, has anyone else experienced this and can anyone suggest anything?

My guess, if this is a .NET project, is that it is the initial JIT compilation that you are seeing.
